直接频率合成仿真源程序,希望有人能用到.-Direct frequency synthesizer simulation source code, hope someone can use to.

利用ps2键盘向单片机输入数据，这样做不仅可以减少输入输出口，而且程序代码短小精悍，可以极大的提高单片机的执行效率．-Ps2 keyboard to use single-chip input data, to do so not only can reduce the input and output port, and program code dapper, you can greatly improve efficiency in the implementation of SCM.

利用单片机测频率-frequency measurement using SCM

HT24 系列的EEPROM 总共8 个管脚，三个为芯片地址脚A0、A1、A2，在单片机对它进行操作时，从SDA 输入A0、A1、A2 数据和芯片外部A0、A1、A2 所接地址需一一对应。一个为芯片写保护脚WP，WP 脚接低电平时，芯片可进行读写操作；WP 脚接高时，芯片只可进行读，不可进行写。 另外两个管脚为电源脚VCC，VSS。 用单片机对HT24 系列的EEPROM 进行控制时，HT24 系列的EEPROM 的外部管脚VCC、VSS、WP、A0、A1、A2 根据需要，对应接上，SDA、SCL 接到单片机控制脚上。-HT24 Series EEPROM total of 8 pins, three pins for the chip address A0, A1, A2, in the microcontroller to operate it, from SDA input A0, A1, A2, and chip external data A0, A1, A2 of the Then one correspondence address must be in. One for the chip, write-protect pin WP, WP feet then low, the chip can be read and write operations WP pin is high then, the chip can only be read, not write. The other two pins for the power pin VCC, VSS. With the microcontroller on the HT24 Series EEPROM control when, HT24 Series EEPROM external pin VCC, VSS, WP, A0, A1, A2 according to the needs of the corresponding connected, SDA, SCL receives SCM control feet .

通信方式是485方式。通过485来控制一组灯的开关。-485 are way communication. Through 485 to control a group of light switches.
